You might not be able to give it a lengthy explanation, but you have definitely felt excessive humidity at some point. When humidity levels are above what is usual, the air feels thick and it almost feels as if you can literally swim through it if you want.

In areas of elevated temperatures and above-average humidity, it can feel like you’re sporting a pullover even if you’re walking around shirtless. This weighty and damp feeling is due to the elevated humidity level.

Perfect Humidity
Most people put comfortable humidity levels somewhere between 25% and 55%. More scientific-based data puts comfortable humidity levels between 30% and 45%. Nevertheless, your perfect interior humidity level is closely related to your individual preferences. Just be sure to never go above 65% or below 25%.

High Humidity Issues
Aside from making you feel warmer, environments with excessive levels of humidity cause various other issues around the house, including fungus, mold, and property damage. Here are some of the issues that you might possibly face in excessive humidity environments:
  • Germs;
  • HDM;
  • Acuter allergies and asthma;
  • Bad-quality sleep;
  • Tiredness, migraines, and heatstroke;
  • Lifeless and foul-smelling plants;
  • Cracked paint and deteriorated wallpaper;
  • Damaged wiring
  • Risk of pest/insect infestation;
  • Mold, mildew, and dampness;
  • Breathing problems;
  • Hypertension.

Even though your AC unit freshens the air through its refrigeration cycle, you might also require a dehumidifier.

Dehumidifier: Basic Information & Types
Essentially, dehumidifier decreases and normalizes air humidity. They are intended for single rooms and multi-story buildings, along with big “industrial” areas, such as factories and storehouses. The kind of dehumidifier you’ll end up picking will depend on your financial situation, house, and personal preferences.
Even though we suggest buying a whole-house humidifier solution to sustain perfect internal humidity levels, you do have a plethora of options presented. Generally speaking, dehumidifiers can be split into the following types:
  • DIY Dehumidifier. Pretty self-explanatory, isn’t it? Believe it or not, there exist numerous ways one can assemble a dehumidifier. Although we CANNOT vouch for it as a long-lasting option, it might be a great option in short term. DIY dehumidifiers can be assembled with charcoal and deicers.
  • Energy Recovery Ventilator (ERV). This one works by utilizing an exhaust fan to send moist air outside. It has a sensor and an exhaust fan. It’s frequently used in cellars, lofts, and crawlspaces.
  • Desiccant Dehumidifier. It’s made of materials with high levels of hydrophilicity, for example – silica gel.
  • Heat-Pump Dehumidifier. Those dehumidifiers require a fan, heat pump, and heat exchanger coils to eliminate humidity from the air. Prices vary from approximately $200 to over $2,000.
How Does a Dehumidifier Work?
Now, let’s get into the basics of dehumidifier operation! Picture yourself drinking a can of coke during an exceptionally hot day. When you pick up your coke, you might notice that it is wet. The wetness is on the outside
As air loses temperature, it starts to lose its water-retention capabilities; the cooler surface pulls and accumulates water from the hotter air, producing condensation. Basically, your dehumidifier works in a very similar way. As mentioned before, most dehumidifiers consist of the following parts:
  • Fan Compressor;
  • Reheater;
  • Condenser Coils;
  • Reservoir.

How do all those components interlock to draw moisture out of the air? It’s rather straightforward but very efficient at the same time. Let’s go into step-by-step mechanics of how do dehumidifiers work!

Just like your imaginary can of coke, the condenser coils are cooler than the air surrounding them. To reiterate: as the air gets colder, its moisture-retention and moisture-capabilities drop, and when the air has more humidity than it can support, it forms that recognizable condensate. The condensate then accumulates in a container for disposal, whilst the now-chilled air moves back to the dehumidifier’s hot motor to be rewarmed before it’s released back into the living space. After being somewhat rewarmed, the air from the dehumidifier is now dried out and hot, which means that it’s now able to attract moisture in an efficient manner, getting the moist out of your dehumidifying unit.

Here’s the shortest version of this explanation.
  • Air is sucked into the dehumidifier by a fan.
  • While the air loses temperature, its moisture condenses
  • Water accumulates in the reservoir.
  • Air is rewarmed.
  • Air is ejected back into the area, it’s now 36°Fahrenheits warmer and noticeably dryer.
  • Self-defrosting mechanism deices the dehumidifier if needed.
  • Dehumidifier turns off automatically once the reservoir is full.
  • When the dehumidifier attains the chosen level of dryness it turns off automatically.

Now that we know how dehumidifier works, let’s wrap this up by listing some of the key benefits of owning such a unit.

High Humidity Issues
Here’s the shortest version of this explanation.
  • They help eradicate allergy triggers, such as dust mites, mold, and mildew.
  • They are not distracting when it comes to your day-to-day life. Most of them run soundlessly and proficiently without anyone even noticing.
  • They aid in decreasing smells that might go along with mold/mildew in your house – eradicating that stale or putrid odor.
  • They aid in lessening the chances of you developing mold on your wardrobe, furniture, drapes, and bedlinen.
  • They decrease irritation to your skin and your ventilatory system.
  • Less humidity means that your clothes will dry quicker, food will remain fresh longer without going bad.
  • Having a dehumidifier helps decrease dust in your house, meaning cleaning your home is going to become a less frequent event.
  • A working dehumidifier also helps save money on electricity bills since it helps your AC unit operate in a more efficient way.
